Grass

Beef that is truly 100 percent grass-fed comes from cows that have grazed in pasture year-round rather than being fed a processed diet for much of their life. Standards and labeling laws for grass-fed beef are controversial and confusing. The terms “grass-fed” or “pasture-raised” are allowed even if your beef really came from cows that spent little or no time outdoors in a pasture setting. U.S. beef labeled as “grass-fed” but not bearing USDA certification may be the result of various combinations of grass and grain feeding including grass finishing. If the label doesn’t specifically say “100 percent grass-fed,” or carry the USDA or similar certification, there’s no guarantee.

Fat is an important ingredient that has a material impact on the nutritional value, texture, taste, shelf-life and producer price of milk. However, milk products are a significant source of saturated fatty acids in the Western diet. How should dairy cattle be fed for their milk to contain more unsaturated fatty acids?

Researchers have found that consuming green vegetables is important to a fully functioning immune system. They do this by ensuring that immune cells in the gut and the skin known as intra-epithelial lymphocytes (IELs) function properly.

We all know that our immune system is the first line of defense against a wide array of potentially deadly pathogens, bacteria and viruses. Yet many people take this crucial defense barrier for granted and do little to ensure that they are adequately protected against a multitude of microscopic invaders. Researchers publish the result of a research body performed at the University of Cambridge in the journal Cell, and they demonstrate that compounds found in green vegetables, from bok choy to broccoli, are the source of a chemical signal that is important to activate a fully functioning immune system.
